This repo provides a set of useful functions for operating on sparsely stored arrays. This is extremely useful for significantly reducing storage and minorly improving runtime when you have high ...

Abstract: Designing sparse arrays with fewer antenna elements and lower peak sidelobe level (PSLL) is critical and challenging for antenna arrays in terminal devices in Internet of Things (IoT) ...

Abstract: Sparse arrays offer a promising solution for reducing the data volume required to reconstruct ultrasound images, making them well-suited for portable and wireless devices. However, the ...

Conventional color printing involves overlaying dots of cyan, magenta, yellow, and black pigments in different ratios to get a spectrum of colors. In the new coloring scheme, each pixel is made of ...

How black is black? An ideally black material would absorb light perfectly at all angles for all wavelengths. Using arrays of carbon nanotubes, researchers based in New York have now engineered a ...

Inkjet or laser? Need just printing, or have to scan and copy, too? Seeking low-cost ink, or a low-cost printer? Here's how to choose the right printer for home or work, backed by our top lab-tested ...
